this one was no easy feat, and involved two 25-megapixel Sony A900 cameras fitted with 400mm Minolta lenses and 1.4X teleconverters, a robotic camera mount from 360world that got the shooting done over the course of two days, and two solid days of post-processing that resulted in a single 200GB file -- not to mention a 15-meter-long printed copy of the photograph for good measure."
